The report presents the results of a new, comprehensive set of experimental data conforming to the irradiation conditions of the derived damage function material, temperature, and fluence. The results of this experiment are discussed in terms of their establishing the validity of the damage function. Averaged values of the damage function are tabulated for a typical reactor physics calculation energy group structure, and their application to two different spectra is described. Finally, the damage-function fluences required to cause a 200F Delta-TT in A302-B steel are presented for many different reactor locations. For each of the spectra involved, the upper and lower energy limits of significantly damaging neutrons are given, and some detail is also provided regarding the contribution of subgroups within the overall energy spectrum.
